摘要
常用的进行数据筛选的方法一般是以样本观测值的某一靠近中心的数据为起点,向样本数据两侧以一定的距离划定范围,然后剔除这一范围之外的数据。因此,具体确定划分范围的标准是一个很重要的问题。现给出一个具体的大样本下的数据筛选标准,并说明使用这一标准的理由和确定这一标准的过程。
The method of data sieving is commonly used on the selection of a sample observation as a starting point,given the range on the both sides of the data point, to reject the samples which is not belong to the range. Therefore, to identify the standard of giving range to the samples is very important. This work is just proposing a concrete standard of data sieving on the large samples, with the reason for using that and also the process of determination.
